3. LSI Interest Group • Status • A prototype LSI Constellation Portal for Mid-Resolution Optical LSI Satellite System Information and Enhanced Data Access was developed in cooperation with CEOS WGISS, and demo’ed at GEO V in Bucharest. • LSI Constellation Portal now operational

6. LSI Interest Group • From presentation by Dr. Bryan Bailey to CEOS SIT, March 2009. • The 2009 LSI Constellation Work Plan focuses on completing and sustaining current and ongoing activities. • LSI Constellation Portal for Mid-Resolution Optical LSI Satellite System Information and Enhanced Data Access will be released by March 31. • In cooperation with WGISS, the LSI Portal will be enhanced to include other LSI satellite system data, as well as increased functionality. • Definition of standards for future mid-resolution, optical satellite systems is scheduled for completion in September. • The WGR likely will focus on facilitating application of CEOS agency radar data to the GEO task on Forest Carbon Tracking and on promotion of operational polarimetric SAR systems. • INPE will complete development of the web-based services or freeware. • The WGRDSC will continue to compile regional data sets and plan for its contributions to GLS2010.

7. LSI Interest Group • From the LSI Constellation 2009 Work Plan • INPE will prepare and circulate plans for development of format conversion and orthorectified image generation capabilities. • The plans will identify the types of information they require from the contributing agencies, and the LSI Constellation Co-Chairs with be responsible for requesting the agencies to provide the needed information. • How might WGISS be of help? • Presentation by Julio Dalge • INPE LSI Constellation Ideas and Plans  

8. LSI Interest Group • Possible areas of LSI Portal enhancements? • Presentation by Paul Davis, University of Maryland • Future Editions under discussion to provide access to LSIC: • Coordinated Sample Data Collections • Attribute search function, via postgreSQL database • Plan prototype interface attachment for map searching • Access open archives for ‘virtual’ searching

11. LSI Interest Group • LSI Portal Next Steps? • Work with LSI Constellation Study Team via Dr. Bailey to identify and prioritize portal enhancements • Possibly pursue some prototype/demonstration enhancements with two or more LSI Constellation members • Demonstrate cross-system, granule level, search and retrieval • Additional attributes • Browse imagery • Geographic query • Possibly employ some standard or non-standard web service interfaces to agency servers • Would need to identify agency information system points of contact and bring them into the portal project team to • participate in defining best, standards-based approach. • Identify possible reuse of an existing query user interface

12. LSI Interest Group • Recommendations to WGISS? • Contact LSI Constellation Study Team to specifically identify next phase enhancements and prepare specific project plan for presentation at next WGISS • Specific support to INPE efforts? • Security Comments? • Simple clearinghouse application presently thus simple security measures • However, if we expand to cross-system, granule level queries, security complexity will increase significantly
